DEMOUNTABLE RIM.

Specification of Letters .Eatent. Patented J 23, 1914 Application filed November 3 1913. Serial No. 7985885.

To all whom it mag concern:

Be it known that I SCHUYLER C. EDDY, a citizen of the United States, residing at Kalamazoo, Michigan, have invented certain new and useful Improvements in Demountable Rims, of whichthe following is a specification.

1 This invention, relates to improvements in demountable rims.

The main objects of this invention are:

First, to provide an improved demountable rim for automobile wheels which may be very quickly and easily placed upon the tire. Second,to provide an improved demountable rim in which the parts are so formed and united that they are not likely to become stuck together by corrosionor so distorted as to prevent their ready disassembling to' remove the tire. Third,- to provide an, improved demountable rim having these advantages which is'very simple and economical in structure and-at the same time, onewhich provides a satisfactory seat and support for the tire and is very convenient to manipulate and durable in use. 1

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow;

I accomplish the objects of my invention by the devices and means described in the following specification. l c

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of'my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I is an elevation of a Wheel embodying the features of myinvention. Fig. H is a radial section through the rim of the Wheel on a line corresponding to line 22 of Fig. I, the tire being indicated by dotted lines. Fig. III is an inside view of the dearrows at the ends of c section lines.

IV is a detail section of the wheel Referring to the drawing, I have shown my improvements embodied in a complete wheel of the artillery type The felly rim 1 in the structure illustrated, 1s of Wood and providetlwith ametal band 2 having a flangelike seat 3 at one side for I the demountable rim. The demountable rim is secured by the wedge members 4 secured by thebolts 5 to clamp and support t-l1e demountable rim as is well understood.

My improveddemountable rim comprises a pair of annular members 6 having tire chan nel flanges 7 at their outer edges. These flanges are adapted to receive the beads of the tire, as is shown in Fig. II, and are of any desired shape for the purpose, depending on the style of tire. At their inner edges, the members 6 are provided with laterally projecting tongues or lugs 8, 9 and 10, the lugs of one member being spaced to interlock with those of the other member. These lugs are offset inwardly to lap within the inner sides of the members, as clearly shown in the drawing. The offsets are substantiall the thickness of the rim members from whic they are formed by stamping or bending.

The lugs engage the inner sides of the Idem: bers and permit thefigiembers to lie edge to edge, forming a su tantially continuous outer surface to receive he tire. See Fig. II.

The lugs interlocksoas to prevent circumferential movement of one member relative to the other. The lugs 10 are provided with keepers 11. Each rim member is provided with several of these lugs 10 havin keepers thereon. The keepers are dispose circ'umferentially of the rim and are engaged by the blade-like lock members 12 pivoted at 13 to swing against the shoulders 14, of the 111 s '9 when the lock members are engaged wit the keepers. These look mom? I bers-are preferably of spring material so thatthey are retained in engagement with the lugs by their own resiliency. The lugs 9 are, in the structure illustrated, longer than the lugs 8. With the lock members thus positioned, they may be readily engaged.

members are enga d and disengaged by an axial movement, t e lugs interlocking so as g toprevent any relative circumferential movement between the arts. This is of great advantage in assembling or mounting the tire on the rim as it is only necessary to engage the channel flanges with the beads of the tire and push the members together edge ,to' edge. The lock members may then be engaged, the tire can be inflated, and the-rim 'is ready for mounting.

ture; for instance, the rim members are.

formed by the same die. The tire may be quickly mounted upon and removed therefrom, and there are no parts to interfere with its being readily slipped upon or removed from the wheel. The ,parts are se- 'curely retained by the Wedges or other means.

I have illustrated and described my im-.

proved demountable rim in a simple embodiment thereof. I have not attempted to illustrate or describe certain modificationswhich I contemplate as. I believe the dis- I closure made will enable those skilled in the art, to which my invention relates to embody and adapt the same as maybe desired. I

. I claim as new and ters Patent is:

desire, however, to be understood as claiming my improvements specifically in the form illustrated as well as broadly within the scope of the appended claims.

Having thus described my invention, what desire to secure by Let- -1. A demountable rim comprisingv a pair of annular rim members provided with channel flanges and having integral later; ally projecting lugs at their inner edges ,interlocking to prevent circumferential movement of one member relative to the other, the lugs being oflset inwardly to lap the inner sides of the members,.a part of the lugs of each member having keepers therein,

and lock members ,of spring material piv-.

oted on said rim members, each lock member ment of one member-relative tothe other, the lugs being ofi'set inwardly to lap the inner sides of the members, the outer faces of-said lugs being disposed fiat against the inner faces of said members, apart of the lugs of each member being rovided with keepers and lock members 0 spring material pivoted on said rim members and disposed tospring'into position to coact with a keeper carried by the opposite rim member, and stop means on said rim members coacting with the body portions of'the lock members carried thereby.

3. A demountable rim comprising a pair of annular rim members disposed edge to edge and provided with axially disposed interlocking lugs ofi'set inwardly to lap the inner sides of the members, the width of the lugs corresponding-to the spaces between the co-a'cting interlocking lugs whereby the members may-be joined and separated by axial movement and are supported against relative circumferential movement, 7 and means for securing said members against axial separation.

. 4. A dcmountable rim comprising a pair.

of annular rim members dis osed edge to edge and provided with latera ly projecting lugs disposed to lap the inner sides of the members and so that the edges of coact-ing lugs are brought into interlocking engagement by axial movement of said members and said members are supported against relative circumferential movement, and

means for securing said members against .a xial separation.

In witness whereofgyI have hereunto set my hand and seal inthe presence of two witnesses.
